自1958年第一台东方红-54拖拉机问世以来,支重台车密封问题就随之而生,厂家多次作过重大改进,但仍未能解决漏油问题。他省在六十年代就将解决支重台车密封漏油列入科研课题,可见支重台车密封漏油是长期以来未能解决好的棘手难题。 支重台车密封漏油即造成浪费,又影响机车的正常作业。为了有效地解决这个难题,提高机车的工作效率和经济效益,浙江省奉化市
Since the advent of the first DF-54 tractor in 1958, there have been many problems arising from the sealing of trolley. The manufacturers made major improvements on many occasions but failed to solve the problem of oil spills. In the 1960s, his province included in the research project a solution to the problem of bearing oil leakage in heavy-duty trolleys. This shows that the problem of heavy-duty trolley-sealed oil spills has long been a difficult one to solve. Leakage of the trolley sealed oil spills caused waste, but also affect the normal operation of the locomotive. In order to effectively solve this problem and improve locomotive efficiency and economic benefits, Fenghua City, Zhejiang Province
